Well, you didn't seem to mention which OS you want to do this on.  For
Win9x/NT/2K/XP, you can use the netstat command and look for established
connections to port 5900 (or 5800; or whatever port VNC is listening
on).  Here's an example from Windows XP Professional:

-----BEGIN EXAMPLE-----
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\Administrator>netstat -an

Active Connections

  Proto  Local Address          Foreign Address        State

<BIG SNIP>

  TCP    192.168.69.100:5900    192.168.69.1:2275      ESTABLISHED

<SMALL SNIP>

C:\Documents and Settings\Administrator>
-----END EXAMPLE-----

So, as you can probably guess, my firewall/router <192.168.69.1> has an
active VNC (APP) connection to one of my PCs at home <192.168.69.100> -- 
this is because I am tunneling VNC through my SmoothWall's SSH service.

HTH...
